Torrefaction of Beech and Spruce Sawdust

Type: article
Abstract: This paper aims to apply a thermal treatment of beech and spruce sawdust dried to 10% moisture in order to determine the mass loss and to obtain pellet sets. This paper considers the colour change of the treated material during the treatment, as function of time and temperature increase. It also highlights the changes in the chemical composition of sawdust connected with the mass loss. The paper also studies the physical integrity of the obtained pellets, using the method of free fall, with the results showing that spruce sawdust pellets appear to be more stable. The optimal temperature of thermal treatment proves to be 2600C and the duration of treatments are 5 and 10 minutes, when the sawdust has dimensions between 0.4-1mm. Regarding the pellets formed at the temperature above 2600C, it should be noted that their stability is low, in particular that one of beech, which is difficult to compress and compact
